But she already knew all the physical facts before she left her room. So, what she learns must be a non-physical fact. Since there are non-physical facts, physicalism is false.
What is Jackson’s argument against physicalism?

Is Frank Jackson a dualist?
“I had been a dualist for years. I was taught by Michael Bradley, and he had some good arguments for dualism. I always thought it was a plausible view. As I say in the beginning of ‘Epiphenomenal Qualia’, we dualists don’t really need an argument to say that consciousness doesn’t fit into the physicalist world view.

qualia include the ways it feels to see, hear and smell, the way it feels to have a pain; more generally, what it’s like to have mental states. Qualia are experiential properties of sensations, feelings, perceptions and, in my view, thoughts and desires as well.
